• 储蓄率是什么？· What is savings rate?
  储蓄率 =（收入 – 支出）/ 收入。它反映的是：你每个周期“真正能留下来”的比例。
  Savings rate = (Income – Expenses) / Income. It indicates how much of your income you actually keep each period.
• 请保持同一口径 · Keep the same basis
  建议你把所有数据都统一为“月”或“年”，不要把月收入配年支出、或把税前收入配税后支出。否则储蓄率会严重失真。
  Use either monthly or yearly numbers consistently. Avoid mixing pre-tax income with after-tax expenses (or vice versa), otherwise the result becomes misleading.
• 收入怎么填更合理？· How to define income?
  如果你的目标是做“预算与现金流管理”，优先使用税后/到手收入（可支配收入）。
  若你更关注“长期财富累积”，也可以把可预期的现金分红/利息纳入收入，但不建议把“未兑现的浮盈”当作收入。
  For budgeting, use after-tax / take-home income. For long-term planning, you may include predictable cash dividends/interest, but avoid counting unrealized gains as income.
• 支出怎么填更准确？· How to capture expenses?
  建议把“每期真实发生的现金流出”尽量覆盖全：
  房租/房贷、吃喝、交通、孩子教育、保险、还款、订阅、礼金、旅行等。
  如果你有大额不定期支出（如年缴保险、车辆保养），可按月摊销（年缴/12）更接近真实水平。
  Try to include all real cash outflows. For irregular big payments (annual insurance, car maintenance), amortize them (annual/12) to get a more realistic monthly figure.
• “结余”不等于“实际存下的钱” · Surplus ≠ actual saved amount
  你可能计算出结余为正，但账户里却没存下钱，常见原因包括：
  ① 口径遗漏（比如信用卡还款没算进去）；② 家庭共同支出没统计完整；③ 现金支出没记账；④ 一次性大额消费。
  这就是为什么本工具提供“储蓄/投资额（可选）”用来核对。
  You may have a positive surplus but still not “see money saved”. Common reasons: missing categories (e.g., credit card payments), incomplete household spending, untracked cash expenses, or one-off large purchases. That’s why we added optional “actual saved/invested” input for cross-checking.
• 如何解读结果？· How to interpret the result?
  这是一个“非常粗但很有用”的指标：越高通常代表越强的现金流控制与积累能力，但也要结合人生阶段。
  经验参考（仅参考） · Rule of thumb (just a guideline):
  • < 10%：现金流偏紧，建议先从“记账 + 降低固定支出”入手。
  • 10%–30%：较健康区间，可进一步做“应急金 + 保险 + 规律投资”。
  • 30%–50%：理财效率较高，重点放在“长期资产配置与风险控制”。
  • > 50%：非常强（或处于特殊阶段），注意是否“过度压缩生活质量”或有一次性收入。
  It’s a rough-but-useful metric. Higher is usually better, but always consider life stage and context.
• 小技巧：用它做“对比” · Use it for comparison
  建议你每月/每季度算一次：对比趋势比单次数字更有意义。比如：储蓄率下降时，去找“固定支出上升”还是“收入波动”。
  Calculate monthly/quarterly. The trend matters more than a single number — when it drops, check whether fixed expenses rose or income fell.

提示：若你的支出大于收入，储蓄率会显示为负数，表示你正在“透支/动用存款/借贷”来维持当前生活方式。可以先从“找出最大支出项”开始优化。
Tip: If expenses exceed income, the savings rate becomes negative, meaning you are drawing down savings or borrowing. Start by identifying the largest expense drivers.
